POMACCI — Fixing E-Scooter Chaos Through Micro-jobs

Designing a mobile app to connect food enthusiasts through shared dining experiences, from concept to prototype.

Role

UX/UI Designer

Industry

Mobility

Duration

3 months

Project Overview

  • In 2024, I worked on PUMACCI, a project aimed at solving parking issues caused by the rapid rise of shared e-scooters in South Korea.

  • Poorly parked scooters blocked sidewalks, caused public inconvenience, and cost the government over 11 trillion KRW annually.

  • Recognizing the growing gig economy among Gen Z, we envisioned a relocation service that incentivized everyday users to reposition scooters properly.

Challenge

The major pain points included:

  • Poor scooter parking behavior leading to significant pedestrian inconvenience.

  • Lack of real-time solutions in existing e-scooter apps to manage parking.

  • Rising complaints and safety issues in dense urban areas.

  • Gen Z’s strong preference for flexible, short-term gig work was untapped.

  • Public dissatisfaction with scooter clutter was at 73%, based on survey data.

  • Gen Z’s strong preference for flexible, short-term gig work was untapped.

  • Public dissatisfaction with scooter clutter was at 73%, based on survey data.

Process

I led and contributed to a structured research and design process:

  • Conducted surveys to understand user behavior and dissatisfaction levels with current scooter usage environments.

  • Investigated the side hustle and gig work trends among Gen Z users, focusing on what motivates participation (e.g., proximity, flexibility, and manageable hours).

  • Mapped user journeys for both scooter users and potential scooter movers.

  • Benchmarked best practices from existing reward apps and e-scooter rental services.

  • Designed wireframes to visualize user flows that incorporated real-time maps, reward systems, and simple relocation actions.

Solution

The final solution introduced:

  • A relocation system where users could find poorly parked scooters, reposition them correctly, and verify their task through a simple photo upload.

  • A gamified rewards system encouraging repeat participation.

  • Real-time scooter availability visualization with a focus on condition, battery life, and parking status.

  • A simple, accessible user flow optimized for quick gig completion.

  • Future scalability for adding community features like leaderboards and badges.

Results

The project successfully:

  • Created a functional prototype demonstrating the user relocation experience.

  • Showed that merging gig economy motivations with mobility service management could lower social costs.

  • Identified clear opportunities for retention through gamified and community-centered strategies.


My Role

  • Led contextual research on Gen Z gig economy behaviors.

  • Designed key UX flows for relocation, verification, and rewards.

  • Conducted competitor benchmarking and user journey mapping.

  • Developed interactive prototypes for usability validation.

  • Proposed system improvements based on real-world usage patterns.


Future Steps / Reflections

  • Plan to implement beacon-based automatic verification for scooter repositioning, reducing the need for manual photo uploads.

  • Aim to build in-app community engagement features, such as rankings and friend invites, to boost long-term user retention.

  • Learned that deeply understanding users’ economic and lifestyle needs leads to stronger service adoption in the gig economy space.
